LIFTlNG-JACK.

SPECIFICATION forming part of Letters Patent N 0. 750,287, dated January26, 1904.

Application filed June 1, 1903. $eria1' No. 159,473. (No model.)

T0 on whom it may concern:

Be it known that I, LUMAN O. KIMBERLY, a citizen of the United States,residing at Oircleville, in the county of Pickaway, State of erates as apry by the use of perpendiculars as a fulcrum; and the objects of myinvention are, first, to provide a convenient lifting-jack for buggies,carriages, wagons, and vehicles generally, and, secondly, to provide aconvenient and useful'post-puller and lifter generally. I attain theseobjects by the mechanism illustrated in the accompanying drawings, inwhich Figure 1 is a sideview of the entire liftingjack viewed from an'angle to the left fore front; Fig. 2, a side view of the lever and itsattachment.

Similar letters refer to similar parts throughout both views.

In Fig. 1, B is the foot or base of the lifting-jack, to which aredetachably secured, the one on each side, the two perpendiculars AA. ffare opposite notches arranged in pairs on the edges of theperpendicularsAA opposite to the handle end of the lever C, said notcheshaving their upper andouter parts turning slightly downward for thepurpose of securely engaging the cross-head 6 when in use. Eachperpendicular has an elongated slot running lengthwise of saidperpendicular, said slots being directly opposite to each other in saidperpendiculars. Each slot has recesses j j arranged in pairs, one ineach pair being opposite the other in each perpendicular, each pairbeing alternately located on each side of each slot for the purpose ofraising or lowering the lever O by engaging its cross-pins h h in anypair of said recesses by sliding the pin up or down the slots to thedesired pair of recesses. I: it are reinforcing-plates attached to thesides of the perpendiculars A A for the purpose of strengthening themwhen necessary.

In Fig. 2, C represents the lever used for prying when the machine isused for vehicles and pulling when it is used for posts and stumps. g isthe ring in'which a chain is fastened for pulling posts and stumps,whereas the top of the lever directly over 9 is placed under the axle ofthe vehicle when it is used for lifting. it h are the two pinsdetachably passing through holes in the lever C. Only 72. is used inprying; but in pulling it is first placed ina pair of recesses j, andthe whole at h is then pried up tothe pair of recesses on the oppositeside of the slot next above it, when the pin it is then inserted throughthe hole and recesses. h is then withdrawn, and its aperture is thenraised to the next pair of recesses on the same side of the slot, whenit is again inserted through the hole of the lever and recesses. It isagain raised to the next pair of recesses on the same side of the slotand the lever pinned there. Then it is again raised to the next pair ofrecesses on the same side of'the slot and the lever pinned there, and soon until the desired height is reached. a is a handle having across-head, one end of which is hinged to C at Z. To the other end ofcross-head is hinged a rod I; at n. The other end of the rod 6 is hingedto the rod 0 at 0. The rod 0 is hinged to the under side of the lever Oat a. On the other end of the rod 0 is the cross-head e. (Z is acoil-spring having one end hinged to the under side of the lever O at qand the other end hinged near the middle of the rod 0 at 12. When thehandle end of the lever O is borne down to lift or pull a weight at theother end of said lever, the handle a is pressed toward (3, which drawsthe cross-head 6 down and engages it in a pair of notches f f, whichholds the weight in place as long as desired. 0 is then disengaged bypressing down the lever O, when the spring d draws it up toward g andprevents it from again engaging, and thus allows the weight to belowered.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

1. In a lifting-jack; a foot or base, having two perpendicularsdetachably secured to it, one near the middle of each side, at rightangles to said foot, said perpendiculars having their broad sidesparallel,and each perpendicular having a slot in the one directlyopposite the slot in the other,said slots running lengthwise of saidperpendlculars and each slot having opposite recesses arranged in pairs,one in each pair being in each perpendicular, each suc.

cessive pair being located, higher and lower, and alternately. in theopposite sides of the slots, substantially as described.

2. In a lifting-jack, a foot or base, having two perpendicularsdetachably secured to it, one near the middle of each side, at rightangles to said foot said perpendiculars having their broad sidesparallel, and each perpendicular having a slot in the one directlyopposite the slot in the other said slots running lengthwise of saidperpendiculars and each slot having opposite recesses arranged in pairsone in each pair being in each perpendicular, each successive pair beinglocated, higher or lower, and alternately in the opposite sides of theslots; and each perpendicular being provided with opposite notches orrecesses arranged in pairs, one of each pair being opposite the other onthe edge of each perpendicular which recesses engage the cross-head ofthe rod holding the lever in position when holding a weight,substantially as described.

3. In a lifting-jack, the combination with a foot and perpendicularsattached to each side of it as herein described, of a lever, one end ofwhich passes between said perpendiculars, having two holes in which pinsare removably placed which pins may be engaged in any pair of recessesin the slots of said perpendiculars; said lever having a T-shaped leveror handle, hinged with one end of its cross-head to its under side nearthe end opposite the perpendiculars, the other end of the crossheadbeing hinged to a rod which extends along the lower side of the leverand hinges at its other end to a rod having a cross-head which hingeswith one end near the middle of the lever then passes down below thelever and between the perpendiculars to their recessed edges where itscross-head may be engaged in any pair of said recesses, substantially asdescribed.

4. In a lifting-jack, the combination with a foot and perpendicularsattached to each side of it a lever one end of which passes between saidperpendiculars, having two holes in said end in which pins are engagedand having a T- shaped handle for lever hinged with one end of itscross-head to its lower edge, near the end opposite the perpendiculars,the other end of the cross-head being hinged to a rod which extendsalong the lower side of the lever and hinges at the other end to across-head rod which hinges with one end to near the middle of the leverand then passes below the lever between the perpendiculars, of acoil-spring attached with one end to the last described rod near itsmiddle and passing obliquely upward attaching at itsother end to thelever near the pins, substantially as described.
